This document explains which steps need to be done to begin using psana modules.  Once you have completed the following you can view a list of more advanced command in the section Common development tasks.

1. Create a test release

...

The newrel command requires two positional parameters: the name of a base release (in this example: ana-current) and the name of a directory which will be created for your test release (in this example: analisysanalysis-rel):

newrel ana-current analisysanalysis-rel

This operation will create the directory and populate it with two files:

% ls  analisysanalysis-rel/
SConstruct
.sit_release

...

These two command should be done just once when you're about to work with that test release.

cd analisysanalysis-rel
sit_setup

3. Create new analysis package (Freq: once)

...

This will create directory my_ana_pkg and populate it with few files and sub-directories:

       .../analisysanalysis-rel/
                      ./my_ana_pkg/
                                   SConscript
                                   doc/
                                       README
                                       ChangeLog

...

mkdir my_ana_pkg/src my_ana_pkg/include   # only if src and include directories do not exist yet
codegen -l psana-module my_ana_pkg my_ana_mod

...

For a python module:

mkdir my_ana_pkg/

...

src  # only if src directory does not exist yet
codegen -l python my_ana_

...

pkg my_ana_mod

The above will create "skeleton" files for an .cpp which contain skeleton code for analysis module.
